私はEI_HOME/confに/ axis2.xmlをして

を追加しました：エラーを以下のスロー

と

<messageBuilder contentType="application/fhir+json" class="org.wso2.carbon.integrator.core.json.JsonStreamBuilder"/> 

成功せず。

Answer 1

は、次のビルダーおよびフォーマッタで試すことができます：

ないと、私はエラーを次の持っている "アプリケーション/ fhir + JSON" のためmessageBuilderとmessageFormatterを追加しますか？このビルダーを使用

<messageFormatter contentType="application/fhir+json" class="org.apache.synapse.commons.json.JsonStreamFormatter"/> 
<messageBuilder contentType="application/fhir+json" class="org.apache.synapse.commons.json.JsonStreamBuilder"/>
